Blockchain Verification Data Storage Method and System Learning

Blockchain Verification Data Storage Method and System Learning

Glossary

Term Definition Blockchain A distributed database that maintains a growing list of data records that are protected by encryption technology to prevent tampering and modification. Block The basic unit in the blockchain, containing transaction data, timestamp, and hash value of the previous block. Block Header A part of the block, containing timestamp, hash value of the previous block, and hash value of transaction data. Transaction Any data change operation recorded on the blockchain, such as transfer or data update. Transaction Value The actual data contained in the block, such as transaction amount, sender and receiver addresses, etc. Hashing An algorithm that converts data of arbitrary length into a fixed-length string. Hash Value A fixed-length string generated by a hash algorithm, used to verify the integrity of data. Node A participant in the blockchain network, responsible for verifying and forwarding transaction information. Validation The process of confirming the accuracy and validity of data or transactions. Encryption Encoding data using a cryptographic algorithm so that it can only be accessed by authorized parties. Digital Signature uses the sender's private key to encrypt data and is used to verify the sender's identity and the integrity of the data. Entity Identifiers are identifiers used to uniquely identify participants in a blockchain network, such as addresses or account names.

Short Answer Questions

Blockchain is a distributed database that ensures data security through encryption technology and a decentralized network architecture. Each block of data is linked to the previous block and is protected using a hash algorithm, and any changes will change the hash value, making it easy to detect.

The system ensures data accuracy by requiring verification by multiple entities related to the transaction. The processing server contacts both parties to the transaction and a third-party verification entity to confirm the validity of the data.

The block header contains a timestamp, a hash of the previous block, and a hash of the current block's transaction data. It acts as a unique identifier for the block and maintains the integrity of the blockchain by linking each block to the previous block.

An entity identifier is used to uniquely identify a participant in a blockchain network, such as an individual or organization. It can be a digital signature, a public key, or other suitable unique identifier.

The requesting entity can provide the individual's entity identifier to the processing server to retrieve the relevant data. The processing server will search the blockchain for transactions containing the identifier and provide the relevant data to the requesting entity.

The system can store and verify a variety of data, such as personal identification information, education and employment history, financial records, medical records, and travel history.

The verification entity is a third-party institution independent of the transaction parties and is responsible for verifying the accuracy of the data. They can provide independent confirmation, such as a government agency, financial institution, or other trusted source.

Compared with traditional databases, blockchain provides higher security, transparency, and tamper-proof capabilities. Its decentralized nature makes it more resistant to single point failures and data leaks.

Hashing algorithms are used to generate block reference values ​​and transaction reference values, ensuring the integrity of the data. Any changes to the data will result in a different hash value, revealing any tampering attempts.

Various entities can benefit from using this system, including individuals, businesses, government agencies, financial institutions, healthcare providers, and educational institutions.
